Visualization of the execution of nested state machines

VizRob

VizRob is a set of visualizations for the execution of nested state machine using execution time and logs produced by the program.

VizRob first conception works with SMACH, a State Machine api for Python: http://wiki.ros.org/smach While VizRob is thought to work with other State Machine APIs, for now it only connection is SMACH. For more information about VizRob, visit: https://mcamp.github.io/VizRob/

vizrob's Issues

when close UI, stop recording info

[SMACH] add error message when something is wrong with a topic subscription

Configuration file

We need a configuration file to install the visualization

Check announcer

In MVMachine>>addCurrentState: there is an announcer, maybe this is not used anymore

Documentation

We need to document how to extend the bridge to work with other apps

Multiple Machine Visualization

For concurrency, there can be multiple machine to visualize at once

When inspecting LogCollection we do not have our visualization

A LogCollection object is a list of logs. It would be useful to have our own visualization working there

red screen on log visualization

Sometimes we get a red screen when updating the logs when the visualization is continuously being updated

write and add 'about' to viz

Documentation for SMACH

We need to document how to use the visualization in SMACH

Add machine without serialization

The SMACH adding machine depends on a serialization.
This serialization is useless, we need to remove it

Give a ROS example that generate logs

This is important since people may have different logging mechanism...

Finish getting data from SMACH

We need to define and implement a way to stop receiving data from SMACH.

For now we are not sure how a program wrote in SMACH communicates that it has been ended. The possibilities are:

• After a few seconds stop the program
• Manual Stop: the user stops manually the receiving of the data
• Look how SMACH communicates that it has been ended

SMACH UI

We should have an UI for starters

Machine Visualization Flickers

The visualization of the machine flickers a lot
We build the view every time because roassal colors and size, it would be better to not build
everything again, just the colors and size, while we keep the position fixed of the elements

Run time visualization

The visualizations work with run-time information, but they are only ready when all the data has arrived.

It would be cool if we show the visualizations at the same time they are receiving the data

do a GitHub.io page

With:

• screenshots
• videos: (i) installation, (ii) how to use it
• Section with the features of VizRob
• Section with the benefits of VizRob

Check NoneState

The NoneState exists because SMACH has 'none' state. Maybe, this should not be in the original API, but in the bridge itself
